To all 'whom it may concern.' f-

.Be it known thatI, CHRISTIAN II. KREIL- ING, a citizen of` they United States, residing atChandlerville,in the county of Cass and 5 State of Illinois, have invented new `and useful AImprovements in Excavating Apparatus, of which thefollowing is aspecication. My invention relates to excavating apparatus'or dredging machines ofthe class especiallyemployed for digging, deepening, or wideningopen ditches, ship-canals, et'c..

`One of the objects of my invention is to provide a power-,driven machine which ,is capable of performing heavy work with lgreat rapidity, and may be readily. manipulated to change .the relation of the several dipper-,operating parts to suit the varying conditions of the work being performed. 2Q To this end I pro-vide a duplex-operating dipper or bucket which is constructed with doors upon opposite ends with locking devices so arranged that the bucketmaybe driven in either direction, thus practically l doubling the vworking capacity of a single i bucket operating in only one direction To.

accommodate the excavator to the varying conditions of the work, Imount the dipper-P beam or stem for universal movement and 3p connect it operatively to opposite'swinging booms. p The advantages of my excavating apparatus willbe clearlyund'erstood from'tha.' following description in connection withthe accompanying drawings, in which-' Figure l is a side elevation of my duplexoperating dipper; Figs. 2 and 3 are respectively end and top lan views of the same;

Fig. 4: is anend e evation of my dredger or excavator; Fig. 5 is a side elevation Vof i" the dredger.

' In the drawings, I have shown my appa# ratus mounted Aupon theframeofthe usual powerI dredge, the ,steam-boiler, engine, and

45 hoisting-drumsbcing illustrated-in .a conventional manner. The boomsB, B, which carry the'hauling and hoistingcables f, connected to'the'dipper or bucket 7c', are pivotally mounted to swing horizontally about.` the central bearing lplate lI-I, fand may be raised or lowered todiiferent heights byV means of the cables h passing over pulleys b .and c. The beam orstem Af, constitutimg the handle of the dipper la, passes through a universal bearing or ball-joint E carried havinga shaft carrying a pinion. g which swung forward or backward about the pivot -block H. By throwing one boom forward upon the outer end 'of the pintle support F, which is swiveled'in the casting M, forming l fthe head of the A-frame having legs C,

firmly supported'and braced in the skeleton frame of the dredge. Thev dipper-beam is, 6o therefore, capable ofvuniversal movement about the pintlesupport F; -The' vertical adjustment vof the dipper-beam A 'is controlled by means of the'friction-wheels I,

engages a rack L on the beam.

Attached to each boom` B is a cable g, which runs on a winding drum N, and'by means of which the booms may be separately and the other backward, jthe dipper or bucket 7c, may be caused to traverse a diagonal pat-h instead of passing straight' across a ditch.

When the dredge boat is to be moved forward toy a new position, the `two booms are swung forward, projecting directly in line Withthe boat, and a 'cable .e is secured to a loo'por hook on the dipper beam. By pull-- ing'upon b othhoisting cables'f, f, the dipper is thrown forward` and dropped upon' the groundL Then by pulling upon the cable 'a th'e boat is drawn forward. After the spuds or anchor-posts Z have been lowered, 'the' booms are 'swung outwardly into-operative position and the hauling cable a is unhooked. vThe dipper or bucket lc is pulled back and forthacrossthe ditch bymeans-of the hoisting cables f,.f, attached thereto and Pasing over the pulleys e, on the booms B, to the winding drums G of 'the hoisting engine.

I .employ a duplex-operating dipper. or

.bucket capable of digging when moved' in eitherdirection, as will more clearly appear from, the deta il views shown in Figs. 1, 2,

and 3. -Thefdipper is open atboth ends, and is provided with a plow orcutting edge Y and with doors P hinged at thetop upon rods a, The doors may swing inwardly, but `are locked against outward -movement by the locking bolts T,.which slide in guides V.- In 'order to prevent' the doors from j swinging:freelyl and thus interfering with each other, a counterweight w.'holds the rdoor 105 back into the dipper when'it is f startingtol load, and a coil spring prevents the door fromswinging back in the way of the other ydoor when loadingi Without these restraining devices, it isevi'dent that the doorsmight l 11.0

connected byumeans vof` a chain o'r .rod'S,.

with a lug X on the pivot-boss of the bail O. During thedigging or filling operation, the bolt T is held downwardI by the .spring U, butwhen the dipper has been .raised to the position shown'in dotted lines inig. 4f,

the lower bail will be swung upwardly, rocking the bell-crank leverV R, wi hdrawing the bolt T, and perrr'iittingA the oortoswing outward to dump the load.

. In the operation of my 'dredgingapparal i tusv, the booms are swung to the'desired posif vvide for the most effective use of my double!v operating .dipper or bucket, I have devised the arrangement' ofj d'oi ible` booms, 4each swing-ing independently about its .pivot-1 tion and the-dipper is. drawn alternatelylby the cables f, f, from one side'ofthe dit-c the ther, the di-pper being lled and 'dumping a load in each direction. The enormous advantages derived vfromi the use of -my du .pleit-operating dipper,'loading or unloading .at each forward or backward stroke, will be appreciated vby engineers. ln order to prowhereby ene may be thrown forward of the other, causing -t e digging-member to trav,

erse a diagonal' path across the line of eX- cavationm such' movement being permitted by the universal movement of theapivotal .support of the dipperI handle or stem. It a pears, therefore, that each of the adjustea le features of the clipper-operating mechanism` coperates to render effective the yconstruction of my duplex-operating dipper.
